To all whom it may concern:

Be it known that we, CARL GUs'rAF HED- BOHM and SVANTE VILLIAM SIXTUsLINDBY, both subjects of the King of Sweden, and residing at Visby, inthe Kingdom of Sweden, have invented new and useful Improvements inGathering-Covers for Holding Papers, of which the following is aspecification, reference being had to the drawings accompanying andforming a part hereof.

Our invention relates to improvements in gathering covers for holdingpapers, letters and the like, of the type in which bows or hooksfastened to the cover are inserted through holes punched through thepaper. In such covers as heretofore constructed it is customary that thepunching of the holes and the insertion of the hooks are two separateoperations, requiring appreciable time and labor.

The object of our invention is to accomplish such a cover in which thepunching of the holes and the insertion of the hooks 1 shall beperformed in one operation and in an automatic manner simply by placingthe paper into the cover and by folding the cover together.

To gain this object our invention consists in a combination with thecover of means for punching holes in the paper, and means for insertingholding hooks into said holes, all of said means being arranged tooperate automatically upon folding the cover, by which combination wesave considerable time and labor. In constructing the cover we use incombination with mechanism for punching the holes another mechanism forlifting the paper so that the punched holes will be located justopposite to the ends of the aforesaid hooks. 1

Our invention is illustrated in the ac companying drawings in which-s-Figures 1, 2 and 3 show sectional end views of the cover and itspunching mechanism, Fig. 4: shows a side View of the punching andlifting mechanisms, Fig. 5 shows Referring to the drawings in detail 1represents the back of the cover, made in two parts hinged together at2. Four hooks 3 are fastened to the back of the cover. Each punchingmechanism comprises two supports 4: formed with a slot in which the pinof the hinge 2 can slide. Between the supports are placed two rotatablesteel rollers 5, and also two plates 6 fastened to the hinge pin. Twopunches 7 are mounted upon one of said plates, the other one beingformed with corresponding dies. Upon the outer side of each plate areplaced two wedge shaped steel bars 9, against which the rollers willpress and thereby cause the movement of the plates. To one of the platesare fastened three springs, of which the two,

designated by 8, will serve to withdraw the paper from the punches 7,and the third one 27, will move the plates apart.

' 11, 11 represent studs, and 12 steel plates fastened to the back andserving to move the supports and the rollers up and down.

Upon the left side of they punching mechanism in Figs. 1-3, is fasteneda plate drum 10 for carrying away the paper chips, to the back of thecover.

The lifting mechanism is illustrated in Fig. 4. It comprises a support13 fastened to the hinges, and equipped at one end with a riser 15, uponwhich a cylinder 14': is ar-.

means of the two angular levers'16 and 18 and the stud 19 fastened toone half of the back which stud will depress-the lever arm 18 when thecover is folded. The cylinder is brought down again by means. ofthespring 17, acting on the angular lever 16.

The punching and lifting mechanisms are prevented from dropping into anoblique position partly by the springs 26 fastened to the back, andpartly by the hinge arrangement 20 and 37 (1F ig. 6). In said hingearrangement a support is located extending upward between the two partsof the back of the cover and adapted to hold the angular lever 18 inproper position and to facilitate its cooperation with angular lever 16.

The locking arrangement is shown in Fig. 5. It consists of a spring 24fastened to one half of the back and provided with a hole arranged toengage a hook or pawl 25 fastened to the other half. The cover is openedthrough the depression of the button 23 by which the rod 22 is turnedand by means of an arm on its inner end lifts the spring 24:, so that itbecomes disengaged from the pawl 25.

The paper is inserted into the cover in the following manner; Bydepressing the button 23 the cover is opened as far as possible (Fig.3), and the paper is placed in the punching arrangement between the leftvhand plate 6 and the springs 8, and also between the springs 21 in bothof the lifting arrangements, the paper being brought down as far as theslots will allow. When the cover is being folded the plates 12 will movethe supports 4 together with the rollers 5 upward in relation to theplates 6, so that the rollers will press against the wedge shaped bars 9and thereby bring the plates 6 toward one another (Fig. 2). The punches7 will then pierce the paper. Upon the continued motion upward of thesupports 4, the rollers 5 will pass over the upper edges of the wedges9, and the spring 27 will move the plates 6 apart, so that the springs 8will withdraw the paper from the punches 7. Immediately thereupon thestuds 19 (Fig. 4) will act on the levers 18 in the two liftingmechanisms so that they will lift the paper just so high that thepunched holes come opposite to the free ends of the hooks 3 when theyare about to meet. The paper will now slide on to the hooks. When thevcover is entirely closed the supports a will have been brought down bythe studs 11 to the position shown in Fig. 1, and are thus locatedtogether with the other parts of the punching and locking arrangementsbe: tween the two wooden parts of the back.

From the above description it is clear that the operation of punchingthe holes in the paper and also the operation of lifting the paper to asuitable height, so that it may be caught by the hooks 3, are bothperformed entirely automatically by the closing or folding of the cover,whereby a considerable amount of labor and time may be saved.
